摘要： 2002—2005年在山西太原、清徐和临汾就旱地冬小麦应用绿色抗旱剂的喷施技术及节水效应进行了研究。结果表明：GDR5号喷施以稀释225倍的增产效果最为显著，其次为稀释300倍和150倍，增产幅度为5.2%~18.5%；GDR5号喷施以起身喷+灌浆（挑旗、抽穗）喷的效果最好，其次为起身喷。增产幅度为10.2%~20.6%；绿色抗旱剂拌+喷试验表明以GDR1号拌种+GDR5号起身期喷施效果最显著。各个绿色抗旱剂叶面喷施的节水效果以GDR5号的较高，其次为GDR2号和GDR1号。该项研究为旱地冬小麦应用生长调节剂开辟了新的领域。

Abstract: The research on spraying technology using GDR and the saving on water effect in dryland wheat was conducted in Taiyuan, Qingxu and Linfen during 2002—2005. The result showed that diluted 225 times, the yield-improving effects GDR5 was the best, the second was 300 times and 150 times, their yield—improving range was 5.2%~18.5%; sprayed during jointing and grouting (heading) the effect was the best, the second was only jointing. their yield—improving range was 10.2%~20.6%. the research of mix and spray on GDR showed that mixing using GDR1 and spraying in jointing using GDR5 the effect was the best. the saving on water effect of GDR5 was the best when each GDR was sprayed, The second was using GDR2 and GDR1. This study opens up a new area for applied grow regulator to winter wheat in dry land.
